Among the potential advantages of using RPHy hydrogels that should be highlighted are the use of visible light instead of UV light, the possibility of precisely modulating the hydrogel mechanical properties that are known to greatly affect cell sensitivity to anticancer drugs [17,18], and the potential selective action on tumor cells since the hydrogel polymerization process could also lead to polymerization of ectopic LYZ found on cancer cells’ surface. The gene discussed is LYZ; the disease is neoplasm.
